Abstract : Virtualization and containerization are two revolutionary technologies that are thoroughly examined in this chapter. The ability to efficiently share processing, storage, and network resources is made feasible by virtualization, as it is detailed in this article. It talks about the function of hypervisors, the isolation of virtual machines, and the adaptability this technology provides. The lightweight virtualization method known as containerization, in contrast, is advertised as packing applications and their dependencies into transportable containers. The process of containerization is covered in detail in this chapter, along with container images, resource separation, orchestration, and the inherent portability of containers.
In addition, the chapter contrasts traditional and virtual architecture's architectural features, emphasizing the transition from physical to digital construction and the consequences of tangibility, materials, iteration, and applications in each strategy.
Both virtualization and containerization's effects on security are covered, with a focus on the necessity of routine patching, access control, and vulnerability testing to reduce any dangers.
The chapter ends by highlighting the importance of these technologies in contemporary computing. It draws attention to their contributions to resource usage optimization, increased flexibility, cost savings, and consistent application deployment from development to production environments. The information in this chapter acts as a thorough reference for comprehending these crucial technologies and the variety of uses to which they are put in the current IT environment.
